4 Claims.

This invention relates to certain new and useful improvements in the spinning art and particular 1 to spinning rings for bar travelers employed in connection with spinning machines.

One of its objects is the provision of a spinning ring of this character which is so designed. as to be self-cleaning and permit the escape of soot, lint and other foreign matter which usually collects upon the spinning ring and its holder, and also to permit of the ready escape of broken traveler wires, thereby eliminating objections which are known to interfere with the smooth running of the traveler and the quality of the product produced by the spinning operation.

Another object of the invention is to provide a spinning ring for bar travelers which is simple, compact, durable and inexpensive in construction, and which is so designed that it does not have to be removed from the supporting base to clean it.

In the accompanying draWing:--

Figure l is a top plan view partly in section of the spinning ring embodying my invention. Figure 2 is an enlarged sectional elevation thereof. Figure 3 is a bottom plan view of one of the holding rings or collars for the spinning ring body. Figure i is an enlarged fragmentary cross section taken in the plane of line 4-4, Figure 1.

Similar characters of reference indicate corresponding parts throughout the several views.

In spinning machines of the character to which my invention is particularly applicable, the threads to be twisted are delivered by feed rolls (not shown) to a take-up spool or bobbin 16 mounted on the usual revolving spindle. Traversing this bobbin is a vertically reciprocating bar 11, the spool extending through an opening 12 in the bar, as seen by dotted lines in Figure 2.

Mounted on the reciprocating bar 11 and surrounding the take-up spool is the usual supporting base or holder 13 for the spinning ring upon which the bar traveler 14 is adapted to revolve. During the operation of the spinning machine, the bar traveler assumes a more or less upright or outwardly directed position and re- -volves with and about the take-up spool, the

thread passing under the traveler before being Wound upon the spool and the bar 11 being reoiprocated so that the threads are uniformly wound in layers upon the spool. The holder 13 may be stamped from sheet metal in the form of a ring, the same having a neck 15 rising from its inner periphery and having upright clamping posts or brackets 16 rising from its outer periphery for detachably receiving and holding the spinning ring in place on the traverse bar.

t its outer edge, this holder has the customary slotted ears 1? for securely fastening it to the bar 11.

The spinning ring for guiding the traveler about the take-up spool consists of an annular body 18 made of a fiber composition or other appropriate material, and in cross section is preferably shaped in the manner shown in Figures 2 and 4, including a substantially semi-circular inner peripheral bearing face merging into an outwardly and upwardly inclined bearing face 19 on its underside with which the traveler legs 20 and bearing arms 21 are adapted to engage, respectively. Depending from its outer edge, the ring-body 18 has a rim or flange 22 and applied to such edge is a retaining or holding means for the ring body consisting of inner and outer rings or collars 23 and 2%, respectively, which form a structure with the ring-body to not only protect it but to also enable it to be fitted to the holder-base 13. The inner collar 23 terminates at its lower edge in a flange or shoulder 25 which overhangs the lower edge of the depending rim 22 of the ring and constitutes a stop for limiting downward displacement of the latter. The outer retaining collar 24 is telescopically fitted over the companion inner collar in clamping relation and terminates at its upper edge in a lateral flange 26 which overlies the adjoining top face of the ring and prevents upward displacement of the ring relative thereto.

The lower edge of the outer retaining collar 24 extends a suitable distance below the lower flanged edge of the. companion inner collar 23 and rests at its lower edge on the top side of the holder-base 13, thereby affording sufficient traveler-clearance between this base and the overhanging bearing face 19 of the guide ring 18. In order to eifectually permit the escape or discharge of soot, lint, fallings from silk and other foreign matter which collect in the traveler space between the ring 18 and the holder-base 13, and which deposits interfere with the smooth operation of the traveler, I have designed the ring to be at all times self-cleaning. To this end, I provide the lower or extended marginal edge of the ring-retaining collar 24 with one or more recesses or openings 2"! which communicate with the traveler-space between the ring and the holder-base and afford discharge ports for the ready escape of any soot or other foreign matter which usually collects on the ring and adjoining parts. These openings also allow for the discharge of broken traveler wires from the traveler-space so that they will not become lodged and interfere with the movement of the traveler. In this selfcleaning operation, the air is continuously circulated about the bobbin and thence travels downwardly and outwardly, creating a draft and thereby aiding in picking up and throwing the foreign material collected between the ring and its base outwardly by centrifugal force through the discharge openings 27.

I claim as my invention:-

1. In a device of the character described the combination of a holder-base and a spinning ring mounted thereon and having a depending peripheral flange terminating at its lower edge at said holder-base and having openings therein for the discharge of soot, lint and other foreign matter, the bottom of said openings being in the plane of the holder base to provide an unobstructed path for the foreign matter.

2. In a device of the character described, the combination of a holder-base, and a spinning ring for a bar traveler mounted thereon and having a depending'flange at its periphery resting at its lower edge on said holder-base to sustain the ring above the base and provide an operating clearance space for the traveler and for the circulation of air, said ring-flange having openings at its lower end on a level with the top side of the holder base and in communication with the traveler clearance space for the centrifugal discharge of soot, lint and other foreign matter.

3. A device of the character described, comprising a holder-base, and a spinning ring including a bearing portion for a bar traveler and interengageable collars telescopically fitted one within the other over the periphery of said bearing portion, each of said collars having an inturned flange at one edge overlying the adjoining top and bottom sides of said body, respectively, the outer collar having portions extending below and resting on said holder-base and other portions terminating short of the top side of said base to provide openings for the discharge of soot, lint and other foreign matter.

4. A spinning ring, comprising a body having a bearing face on its underside and a depending rim encircling the same, a collar fitted over the periphery of said body and having an inwardly-facing flange at its lower edge forming a stop shoulder against which the lower edge of said body-rim is adapted to bear, and a clamping collar encircling said-flanged collar and having an inwardly-facing flange at its upper edge overlying the adjoining top face of the ring-body, said clamping collar extending below the flanged collar and having downwardly-opening notches therein forming discharge openings.
